Comparative analysis of mycoplasma ribosomal RNA operons

Using differential probes derived from the Escherichia coli rrnB operon, we were able to map the ribosomal operons of Mycoplasma pneumoniae, M. hyorhinis, and M. arthritidis. All organisms contained only one ribosomal RNA operon, and the genes were linked in the eubacterial order, 16S-23S-5S. The HindIII sites in M. hyorhinis and M. pneumoniae were highly conserved.
